PLAN THE DUCTWORK

!WARNING

PERSONAL INJURY HAZARD

Because of the weight and size of the rangehood canopy, two or more people are needed to move and safely install the rangehood canopy.

Failure to properly lift rangehood could result in damage to the product or personal injury.

PLAN THE DUCTWORK

The Magnum rangehood is designed to offer wide flexibility of installations. The rangehood can be ducted vertically or horizontally through a 6" round vent. The unit can also be installed in a recirculating configuration. FIGURES 1 and 2 show vertical and horizontal installations for this unit. FIGURE 3 shows recirculating installation.

The Magnum requires 6" round ductwork. To ensure that the blower performs to its highest possible capacity, ductwork should be as short and straight as possilbe.

WARNING! BEFORE MAKING ANY CUTS OR HOLES FOR INSTALLATION, DETERMINE WHICH VENTINGMETHODWILLBEUSEDANDCAREFULLY CALCULATE ALL MEASUREMENTS.

CALCULATE THE DUCTRUN LENGTH

The ductrun should not exceed 35 equivalent feet if ducted with the required minimum of 6" round duct. Calculate the length of the ductwork by adding the equivalent feet in FIGURE 4 for each piece of duct in the system. An example is given

45˚ Elbow

 

3.0 feet

 

90˚ Elbow

 

5.0 feet

 

90˚ Flat Elbow

12.0 feet

 

Wall Cap

 

0.0 feet

For best results, use no more than three 90° elbows. Make sure that there is a minimum of 24" of straight duct between elbows if more than one is used. Do not install two elbows together. If you must elbow right away, do it as far away from the hood's exhaust opening as possible.

RECIRCULATING INSTALLATIONS

For recirculating installations, Charcoal Filters are necessary. Remove all grease filters and set aside. Attach one charcoal filter to each end of the blower. Each charcoal filter attaches to the black grid on the side of the blower. Rotate the filter clockwise to install and counterclockwise to remove (FIGURE 3C). Replace all grease filters. Some ductwork must be installed to exhaust the rangehood back into the kitchen, either at the top of the cabinet (FIGURE 3A) or at the face or side of the soffit (FIGURE 3B). This duct work must not terminate into a dead air space.
